The center-of-mass energy is $10.58$ GeV. From a fit to the distribution of the energy-substituted mass $m_{\\mathrm{ES}}$, the result $\\mathcal{B}(B^0\\rightarrow p p \\bar{p} \\bar{p})=(1.1 \\pm 0.5 \\pm 0.2) \\times 10^{-7}$ is extracted, where the first uncertainty is statistical and the second is systematic. The significance of the signal is $2.9$ standard deviations.
